xfs_put_perag() is paired with xfs_get_perag() and should never be
called by itself. It is a stub for AG reference counting the
in-memory per-ag structures and, in future, locking to allow us to
avoid certain deadlocks that can occur (rarely) when growing and
shrinking the filesystem.

Also, I've got patches that put stuff in this function, so I'd
prefer to leave it as it is right now...

Cheers,

Dave.
